                                     PART I


ITEM 1.  BUSINESS

         The following discussions contain forward-looking statements regarding
future events or the future financial performance of Censtor Corporation, (the
"Company" or "Censtor") that involve risks and uncertainties. The Company's
actual results could differ materially from those anticipated in these
forward-looking statements as a result of certain factors, including those set
forth in the documents the Company files from time to time with the Securities
and Exchange Commission.

         GENERAL

         Censtor was incorporated in 1981, and until early calendar 1996, had
been focused on developing technology for and manufacturing high performance
contact recording heads and media for the computer disk drive industry. The
Company has been unable to raise the capital required to pursue its former
strategy of manufacturing contact recording heads and, accordingly, on July 18,
1996, the Company completed a transaction with Read-Rite Corporation
("Read-Rite") to concentrate its efforts on licensing rather than licensing and
manufacturing. The transaction with Read-Rite (the "Read-Rite Transaction")
involved the purchase by Read-Rite of Censtor's manufacturing and research and
development operations including the tangible assets, contracts and lease
liabilities related thereto together with a grant by Censtor to Read-Rite of a
non-exclusive license to Censtor's patents and other intellectual property
rights related to the Company's technology.

         The Company owns or has applied for fundamental patents pertaining to
micro-miniature, low-cost read/write heads and special surface treatments for
disk media that allow continuous head/disk contact during operation ("contact
recording") without excessive wear. Most heads available commercially are
designed to operate at a microscopic distance or "fly" above the surface of the
disk on a cushion of air and come into true contact with the disk only when the
drive is turned off or "powered down." Historically, increases in areal density
(the number of bits of data stored in a unit of area, usually quoted in square
inches, on the surface of the recording disk) have come primarily from
reductions in flying height. Contact recording has not been possible because of
the excessive wear and crash problems inherent in operating conventional head
designs in continuous contact with the disk media. The Company believes that
Censtor technology solves these problems.

         The Company's present business model calls for the Company to license
contact recording technology to disk drive manufacturers and then to transfer
the technology to them or their designated head and disk suppliers for
production of heads, media and disk drives. Currently, Censtor has sold licenses
to nine disk drive and disk drive component manufacturers (IBM, Fujitsu,
Hitachi, Maxtor, NEC, MiniStor, Western Digital, Denka and Read-Rite) who bought
the licenses based upon their expectations that the Company's technologies may
be used in the future. To date, however, no products utilizing the Company's
technology have been introduced and there can be no assurance that such products
will ever be introduced or marketed. Although certain of the Company's licenses,
including the Read-Rite license, do not bear royalties, the Company believes
that if Read-Rite or another licensee introduces products using Censtor
technology, licensees with royalty-bearing licenses and potential licensees will
be encouraged to develop, introduce, and manufacture their own products
utilizing this technology.

         BUSINESS STRATEGY

         Censtor's strategy is to perfect its patent protection and proprietary
rights to the disk drive technology developed by it over the last 14 years, and
to exploit that technology through licensing or other strategic transactions
with disk drive manufacturers and other related companies.

         MAINTENANCE AND ENHANCEMENT OF PATENT PORTFOLIO

         To protect and enhance its large investment in head and media
development, the Company maintains an aggressive patent prosecution strategy and
has obtained several patents covering low mass recording heads. The Company's
patent portfolio currently includes 17 issued United States patents, 14 pending
United States patent applications, ten foreign patents and a number of foreign
patent applications. With respect to its micro Flexhead(R) components in
particular, the Company has three issued United States patents covering the
structure, manufacturing process for and application of low-mass contact
recording devices and two additional United States patents covering improvements
and advances relating to those patents. The Company believes its patents may
create substantial barriers to entry for competing technologies which
incorporate heads with very low effective mass for either contact or flying head
recording.

         SALES, MARKETING AND DISTRIBUTION

         By creating license relationships with disk drive manufacturers, the
Company has been building a base of potential customers for components using its
technology. The Company has initially targeted disk drive companies focused on
the personal computer and small form factor market segments where the Company
believes the advantages of its technology should be most compelling. Integrated
computer and disk drive or component manufacturing companies have recognized
that low mass contact recording is likely to be required to achieve the
increases in areal storage densities necessary to sustain future drive product
generations. These companies have shown a willingness to invest today in order
to acquire access to and start learning to use what they perceive may be an
important recording technology in the future. Accordingly, the Company has
already sold licenses to several such companies, including IBM, Fujitsu, NEC,
Denka, Hitachi, and most recently Read-Rite and Western Digital as well as OEM
disk drive manufacturers Maxtor and MiniStor.

         MiniStor, which was operating under protection of Chapter 11 of the
United States Bankruptcy Code, has sold all of its assets and is no longer
operational. However, the Company is not dependent upon, nor did it plan to
derive a significant portion of its revenues from, sales to MiniStor.

         RESEARCH AND DEVELOPMENT

         The Company had been spending between $8.0 million and $12.0 million
annually over the last three years on its research and development activities.
These R&D operations have been assumed by Read-Rite as part of the Read-Rite
Transaction, and all of the Company's R&D employees have accordingly been hired
by Read-Rite as of February 1996.

         MANUFACTURING ACTIVITIES

         The Company's former manufacturing operations have been assumed by
Read-Rite as part of the Read-Rite Transaction and all of the Company's
manufacturing employees have been hired by Read-Rite. Accordingly, the Company
has focused its efforts on licensing its technology and will rely on its
licensees and their designated suppliers to manufacture any products based upon
the Company's technology.

         COMPETITION AND TECHNOLOGICAL CHANGE

         The disk drive component industry is intensely competitive.
Participants in the industry include both independent component suppliers as
well as large disk drive and computer manufacturers that supply their internal
component requirements. These companies have greater financial, marketing and
technological resources than the Company. The Company also competes with
companies offering products based on alternative data storage and retrieval
technologies. Technological advances in magnetic, optical, semiconductor or
other technologies, or the development of new technologies, could result in the
introduction of competitive products with superior performance to and
substantially lower prices than the Company's technology can provide, which
could render the Company's technology noncompetitive or obsolete, thereby
adversely affecting the Company's results of operations.


                                      -3-
<PAGE>   4
         The market for the Company's technology is intensely competitive and
characterized by rapidly changing advances in head and media technologies. These
advances result in frequent product introductions, short product life cycles and
increased product capabilities that may result in significant performance
improvements and price reductions. Specifically, the Company is subject to
competition from manufacturers of thin film inductive and MR heads, as well as
thin film media based on use of conventional flying head and longitudinal
recording technologies. Head and media product performance has been improving
steadily due to a combination of increased transducer efficiency, improved media
performance, smaller slider size, lower flying heights, and pseudo-contact heads
and it is expected to continue to improve. In addition to enabling lower flying
heights, the cost of advanced inductive flying heads is being decreased by the
reduction in the size of the slider, which permits fabrication of more sliders
per wafer. There can be no assurance that the Company's potential performance
and manufacturing cost advantages will be realized in practice or can be
maintained over the improvements to conventional inductive heads.

         LICENSES WITH DISK DRIVE AND COMPONENT MANUFACTURERS

          As of September 15, 1996, the Company had entered into license
agreements with seven of the roughly twenty-five disk drive manufacturers in the
world: IBM, Fujitsu, Hitachi, Maxtor, MiniStor, NEC, and Western Digital, and
with two component manufacturers - Denka and Read-Rite. The Company has executed
license agreements with initial license fees of $25.5 million from these
licensees (including $8.0 million associated with the Read-Rite Transaction,
certain portions of which are subject to offset as described in "Management's
Discussion and Analysis of Financial Condition and Results of Operations".) In
addition, the Company has received $7.5 million of non-refundable advance
royalty payments. Some of these agreements provide that no future licenses
granted by the Company will be more favorable than the existing licenses and
that the licensee may grant restricted sub-licenses to component suppliers.
Others permit the licensees to acquire the right to appoint subcontractors in
exchange for the payment of additional license fees and royalties. The specific
terms of the license agreements vary depending on when the licenses were entered
into, whether or not the Company has rights to future royalty payments from the
licensee, whether the license extends to not only the Company's patents but also
its trade secret information, and whether the licensee is expected to become a
component supplier. In August 1996, the Company entered into a world-wide,
non-exclusive license agreement with Western Digital Corporation by assigning a
Promissory Note between a subsidiary of the Company and Western Digital to
Censtor and converting this Note to a license.

         ENVIRONMENTAL REGULATIONS

         The Company has been subject to a variety of governmental regulations
relating to the use, storage, discharge, handling, emission, generation,
manufacture and disposal of toxic or other hazardous substances used to
manufacture and test the Company's micro Flexhead(R) component. The Company
believes that as of the closing date of the Read-Rite Transaction it was in
compliance in all material respects with such regulations and that it had
obtained all necessary environmental permits to conduct its business. Any
failure in the past by the Company to control the use, disposal or storage of,
or adequately restrict the discharge of, hazardous or toxic substances could
subject the Company to significant liabilities and could significantly reduce
the amount of the final $2.0 million payment due from Read-Rite in April 1997.

         HUMAN RESOURCES

         As of June 30, 1996, the Company had 6 full-time employees, all engaged
in general and administrative functions. The Company is highly dependent upon
certain members of its management team, the loss of service of one or more of
whom could adversely affect the Company. The Company has only limited
management, operational and financial resources and the Company's success will
depend in large part on its ability to retain and, if necessary, attract skilled
and experienced employees. None of the Company's employees is covered by a
collective bargaining agreement or employment contract and the Company considers
its relations with its employees to be good.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS
         Unless otherwise indicated, references to years in this
         section refer to fiscal years ending June 30.

         The following discussion and analysis contains forward-looking
statements regarding future events or the future financial performance of
Censtor that involve risks and uncertainties. The Company's actual results could
differ materially from those anticipated in these forward-looking statements as
a result of certain factors, including those set forth in the documents the
Company files from time to time with the Securities and Exchange Commission.

RESULTS OF OPERATIONS

         OVERVIEW

         The Company was formed in 1981 to develop perpendicular recording
technology, and to manufacture head and disk components for disk drives. The
Company subsequently shifted the focus of its development efforts from
perpendicular to longitudinal contact recording technology. To date, the
Company's principal source of revenue has been license fees from disk drive
manufacturers. While the Company's license agreements typically provide for
on-going royalty payments by licensees based upon sales of products
incorporating the Company's technology, to date none of the Company's licensees
has commercialized products using the Company's technology and the Company has
received no recurring royalty revenue. The Company has not been profitable in
any fiscal period since inception and, as of June 30, 1996, had an accumulated
deficit of $107.9 million. There can be no assurance that the Company will
achieve or sustain significant revenues or profitability in the future.

         Censtor's operating plans for fiscal 1997 focus on the perfection of
the Company's patent protection and other proprietary rights and the possible
exploitation of such rights through licenses or other strategic transactions
with disk drive manufacturers and other related companies. The Company expects
to finance these operations through payments from Read-Rite in connection with
the Read-Rite Transaction and possibly through sales of additional licenses.
There can be no assurance that the Company will be able to sustain its
operations beyond 1997 without the sale of such additional licenses.

         LIQUIDITY AND CAPITAL RESOURCES

         Since its inception, the Company has financed its operations primarily
through private placements of its equity and debt securities and, to a lesser
extent, through licensing and research and development agreements. During the
fiscal year ended June 30, 1994, the Company generated net cash from financing
activities of $17.7 million, primarily reflecting the sale of Series B
Convertible Preferred Stock. In 1995, net cash provided by financing activities
was $832,000, resulting primarily from proceeds of $2.0 million from the sale of
preferred stock of a subsidiary of the Company which was partially offset by
$1.1 million of principal payments on capital leases. In 1996 the Company
generated net cash of $6.6 million resulting primarily from $7.5 million in
Notes Payable and short term borrowing offset by $1.4 million in capital lease
payments. During fiscal 1994, 1995 and 1996, the Company used net cash in its
operations of $13.2 million, $8.3 million, and $8.1 million respectively. In
1995 and 1996, the Company received payments of license fees and non-refundable
prepaid royalties from several licensees, which caused net cash used in
operations to be less than the Company's net loss. In addition, particularly in
1995 and 1996, the Company delayed payments on accounts payable to conserve cash
prior to completion of then-anticipated new financing.

         The Company generated net cash from investing activities of $1.0
million in 1994 consisting of $1.7 million used for additions to property and
equipment and $2.8 million provided by proceeds from the sale and leaseback, and
sale of fixed assets. In 1995, with a similar transaction, the Company generated
net cash from investing activities of $205,000 consisting of $379,000 used for
additions to property and equipment and $584,000 provided by proceeds from the
sale and leaseback, and sale of fixed assets. In 1996 the Company


                                      -9-
<PAGE>   10
generated net cash from investment activities of $358,000 consisting of $192,000
used for additions to property and equipment and $550,000 provided by proceeds
from the sale and leaseback, and sale of fixed assets.

          The Company's ability to fund its cash requirements through fiscal
1997 depends largely upon its success in collecting $2.5 million from Read-Rite,
the remainder of the aggregate purchase price of $9.0 million for the assets and
license sold in the Read-Rite Transaction. This hold-back amount is payable to
the Company in installments from November 15, 1996 through April 18, 1997,
subject to certain conditions, and is subject to reduction for any claims by
Read-Rite for damages in the event the Company breaches or has breached the
Asset Sale Agreement or License Agreement entered into by the Company in
connection with the Read-Rite Transaction. The Company is not aware of any such
claims at the present time. The Company also continues to seek new licensees.
However, there can be no assurance that the Company can enter into a new license
agreement in fiscal 1997 or at any subsequent time. Any such failure would have
a material adverse effect on the Company's business, financial condition and
results of operations. The Company's commitments for cash payments in fiscal
year 1997 are primarily for operating expenses, which are currently expected to
decrease, in the aggregate, as compared to operating expenses incurred during
fiscal 1996 due to the Company's reduction in size and scope of operations. See
"Note 2 of Notes to Consolidated Financial Statements."

         If the Company is successful in collecting a significant portion of the
remaining fee due from Read-Rite, which it anticipates doing, it believes that
it will be able to finance its operations during fiscal 1997. There can be no
assurance, however, that the Company will be successful in this endeavor or that
the amount actually collected will be adequate to fund the Company's operations.

         RESULTS OF OPERATIONS

         Revenues

         The Company's major revenue source has been fees from license
agreements with disk drive manufacturers. License fees are generally recognized
over the estimated period in which the Company expects to provide support in
connection with the license. All deferred revenue pertaining to licenses sold to
disk drive manufacturers have been recognized as revenue in fiscal 1996 since
the Company can no longer provide technical support to its licensees as a result
of the Read-Rite Transaction. The license fee from Read-Rite in connection with
the Read-Rite Transaction will be recognized over a period of six years.

         The Company's revenues were $7.8 million, $3.5 million and $3.2 million
in 1994, 1995 and 1996 respectively. Of these revenues, approximately $1.8
million in 1994 represented revenues from related parties. In June 1993, the
Company entered into a license agreement with IBM, which contributed $4.1
million to the Company's revenues in 1994. In addition, in October 1993, the
Company entered into a technical assistance agreement, whereby the Company
granted the right to priority access by Daido to training and technical
assistance by the Company in developing manufacturing capabilities for certain
components. The Company received approximately $1.7 million from Daido in fiscal
year 1994 under this agreement. The Daido agreement expired in October 1994.
Revenues in 1995 consisted primarily of the amortization of the Hitachi license
that was sold in December 1994. Revenues in fiscal 1996 consisted primarily of
the continued and complete amortization of the Hitachi license fee as well as
the NEC license sold in August 1995.

         Research and Development

          Research and development ("R&D") expenses decreased slightly from
$11.7 million in 1994 to $11.4 million in 1995, and decreased significantly to
$8.3 million in 1996. This large decrease is attributed to Read-Rite's hiring of
most of Censtor's employees on February 5, 1996 and subsequent acquisition of
the Company's research and


                                      -10-
<PAGE>   11
development operations. In the future, as a result of the Read-Rite Transaction,
the Company expects no material R&D expenses.

         Selling, General and Administrative Expenses

         Selling, general and administrative expenses increased from $2.4
million in 1994 to $2.8 million in 1995 and decreased to $2.4 million in 1996.
The increase in 1995 resulted primarily from an increase in legal fees for
patent filings and legal fees associated with establishing a subsidiary. The
decrease in 1996 was due to reduction of the use of outside legal counsel for
patent filings because the Company hired an "in-house" patent counsel in April
1995.

         Interest and Other Income (Expense)

         Interest expense consists primarily of interest on the Company's
outstanding indebtedness and capital leases. Interest expense decreased from
$1.7 million in 1994 to $1.1 million in 1995 and increased to $1.2 million in
1996. The decrease in 1995 is attributable to the pay down of existing leases.
The increase in 1996 was caused primarily by interest on certain investor notes,
a bank loan, and Promissory Notes provided by Read-Rite offset by the pay down
of existing leases.

         Interest income is the result of interest earned on the temporary
investment of the Company's cash pending its use in operations. Interest income
decreased from $200,000 in 1994 to $173,000 in 1995 and to $5,000 in 1996. This
large decrease in 1996 was due to the substantial decrease of the Company's cash
balances in interest bearing accounts over the course of the year.

         Income Taxes

         As of June 30, 1996, the Company had federal net operating loss and
credit carryforwards of approximately $98.0 million and $3.3 million,
respectively, expiring in various years beginning in 1997 through 2010. The
Company also has state net operating loss and credit carryforwards of
approximately $31.0 million and $1.2 million respectively. The state operating
loss carryforwards will expire in various years beginning in 1997 through 2001
while the credit carryforwards will expire in various years beginning in 2003
through 2011. Tax law provides that the use of net operating loss and credit
carryforwards are restricted if there is a substantial change in the ownership
of the Company. Due to prior years' equity transactions, such a change has
occurred. Approximately $75.0 million of federal net operating loss and all
credit carryforwards are subject to an annual limitation. The annual limitation
is approximately $1.2 million per year. The balance of $22.0 million federal net
operating loss carryforwards can be used without limitation. Similar limitations
apply to state carryforwards. A subsidiary of the Company has a federal net
operating loss carryforward of approximately $7.5 million. Income tax expense
in 1995 and 1996 represents foreign withholdings in connection with license 
agreements.

         Effect of Inflation

         The Company believes that inflation has not had a material impact on
its operating or financial ratios during the year ended June 30, 1996 as
compared to the years ended June 30, 1995 and 1994.

ITEM  13.         CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         The Company's Bylaws provide that the Company is required to indemnify
its officers and directors to the fullest extent permitted by California law,
including those circumstances in which indemnification would otherwise be
discretionary, and that the Company is required to advance expenses to its
officers and directors as incurred. Further, the Company has entered into
indemnification agreements with its officers and directors. The Company believes
that its charter and bylaw provisions and indemnification agreements are
necessary to attract and retain qualified persons as directors and officers.

         In December 1995, Edwin V.W. Zschau, the Chairman of the Board of the
Company, entered into a one year consulting agreement with the Company, whereby
the Company would pay Dr. Zschau $7,500 per month for up to three days service
per month to help develop and implement the Company's financing strategy as well
as for participation as a member of the Company's Board of Directors. Dr. Zschau
subsequently worked 30 days on the behalf of the Company during the period
December 1995 through March 1996, culminating with the Company entering into a
Letter of Intent with Read-Rite. The Company's Board agreed to modify this
agreement to pay Dr. Zschau $75,000 for the 30 days of work through March 31,
1996, and to terminate any future payments for consulting on financial strategy
issues. Dr. Zschau will be paid for attendance at Board of Director's meetings.

         On January 31, 1996 the Company's Board of Directors approved a six
month performance bonus, amended on April 2, 1996, of approximately $137,500 to
be paid in semi-monthly installments commencing April 23, 1996, for Garrett A.
Garrettson.

         Additionally, certain shareholders beneficially owning more than 5% of
the Company's capital stock have made loans to the Company in the first calendar
quarter of 1996. Fifty percent of the principal balances of these loans plus
accrued interest on that portion were repaid from the proceeds received by the
Company at the closing of the Read-Rite Transaction, while the remainder plus
accrued interest on the remaining portion will be repaid in April 1997.

         The Company believes that all of the transactions set forth above were
made on terms no less favorable to the Company than could have been obtained
from unaffiliated third parties.

                REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Shareholders
Censtor Corp.

We have audited the accompanying consolidated balance sheets of Censtor Corp. as
of June 30, 1995 and 1996, and the related consolidated statements of
operations, net capital deficiency, and cash flows for each of the three years
in the period ended June 30, 1996. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Censtor Corp. at
June 30, 1995 and 1996, and the consolidated results of its operations and its
cash flows for each of the three years in the period ended June 30, 1996, in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                  June 30, 1996

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      The Company

      The Company licenses technology related to recording heads and storage
media utilizing contact magnetic recording technology. The Company licenses its
technology to disk drive and component manufacturers. In June 1995, the Company
formed a new subsidiary, Contact Recording Technology, Inc. (CRT), to develop
and manufacture contact longitudinal data storage heads for the computer disk
drive industry. The Company received an approximate 89.5% interest in the
subsidiary in exchange for agreements to license certain technology and to
provide certain services to the subsidiary. The remaining 10.5% interest was
sold to two outside investors for $2,000,000.

      In September 1995, a potential third outside investor/joint venture
partner was issued a warrant to purchase 250,000 shares of preferred stock of
CRT at an exercise price of $4.00 per share, exercisable through December 31,
1995. The investor exercised the warrant to purchase a total of 135,000 shares
for a total of $540,000 for an approximate equity interest of 2.7%.

      Consolidation

      The accompanying consolidated financial statements include the accounts of
the Company, CRT, and its wholly owned subsidiary, Censtor Media Corp. (Media),
an inactive research and development company.

      The Company considers all highly liquid debt instruments purchased with a
maturity of three months or less to be cash equivalents. The Company invests
excess cash in money market funds with a local bank and a large, well-rated
financial institution. These investments are generally available upon demand and
are collateralized by the assets of the bank and the financial institution.

      Revenue Recognition

      License fees are generally recognized over the estimated period in which
the Company expects to provide support in connection with the license.

      Royalties from licensees on sales of licensed products will be recognized
when products incorporating the Company's technology are shipped by the
licensees or when nonrefundable payments are received (see Note 2).

      Property and Equipment

      Property and equipment are stated at cost and are depreciated on a
straight-line basis over the estimated useful lives of five years. Assets under
capital leases and leasehold improvements are amortized on a straight-line basis
over the lease term or their estimated useful lives, if shorter.

      Property and equipment under capital lease obligations have a capitalized
value and net book value of $3,527,828 and $1,887,579 at June 30, 1995 and
$3,444,789 and $814,886 at June 30, 1996. Amortization expense on assets under
capital lease obligations is included in depreciation and amortization.

      Long-Lived Assets

      In 1995, the Financial Accounting Standards Board released Statement of
Financial Accounting Standards No. 121, "Accounting for Impairment of Long-Lived
Assets and for Long-Lived Assets to be Disposed Of" (FAS 121). FAS 121 requires
recognition of impairment of long-lived assets in the event the net book value
of such assets exceeds the future undiscounted cash flows attributable to such
assets. FAS 121 is effective for the fiscal years beginning after December 15,
1995. The adoption of FAS 121 is not expected to have a material impact on the
Company's financial position or results of operations.

      Accounting for Employee Stock Options

      In October 1995, the Financial Accounting Standards Board issued Statement
of Accounting Standards No. 123, "Accounting for Stock-Based Compensation" (FAS
123). The Company will be required to adopt FAS 123 in 1996. The Company's
intention is to continue to account for employee stock options in accordance
with APB Opinion No. 25 and to adopt the "disclosure only" alternative described
in FAS 123.

      Use of Estimates

      The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

      Net Loss Per Share

      Net loss per share is computed based on the weighted average number of
shares of the Company's common stock. The Company's common stock equivalent
shares from convertible preferred stock and from stock options and warrants were
antidilutive for each of the three years ended June 30, 1994, 1995, and 1996
and, accordingly, were not included in the weighted average number of shares.

      Major Licensees

      In fiscal 1996, one licensee comprised 34% of revenues. In fiscal 1995 and
1996, a second licensee comprised 82% and 64% of revenues, respectively. In
fiscal 1994 and 1995, a third licensee comprised 13% and 10% of revenues,
respectively. In 1994, a fourth licensee (a related party) comprised 22% of
revenues, a fifth licensee comprised 12% of revenues, and a sixth licensee
comprised 53% of revenues.

2. SALE OF ASSETS

      On March 29, 1996, the Company entered into an agreement (the Agreement)
with an established component manufacturer in the disk drive industry (the
acquirer), which provided for the transfer to the acquirer of the Company's
research and development operations, including substantially all of the
Company's employees and the sale of certain of the Company's physical assets and
rights and obligations under contracts related thereto on the closing date of
the Agreement. The Agreement was approved by the Company's shareholders on July
11, 1996 and closed on July 18, 1996. Upon the closing, the Company granted to
the acquirer a nonexclusive, irrevocable worldwide license covering the
Company's intellectual property, including the Company's rights in patents,
technology, and software.

      Gross proceeds to the Company under the Agreement are $9,025,000, subject
to certain adjustments under the Agreement, of which $6,525,000 was payable upon
closing with the balance receivable in installments from November 15, 1996
through April 18, 1997, subject to certain conditions. The gross proceeds were
reduced by approximately $1,900,000, related to partial repayment of the
outstanding balance on notes payable to the acquirer. The remaining balance on
the notes payable of approximately $450,000 was forgiven.

      Of the total proceeds, $8,000,000 was in consideration for the grant of
the license and $1,025,000 for the sale of assets and transfer of the assembled
workforce.

      The Company will recognize a gain of approximately $700,000 in connection
with the sale of assets and the transfer of the assembled workforce in fiscal
1997.

      Of the net proceeds, the Company used $3,603,759 to pay down obligations
due as of the closing date, including $2,000,000 to partially repay outstanding
accrued interest on the subordinated debentures (see Note 3), $597,787,
including accrued interest of $51,112 to partially repay the convertible
promissory notes (see Note 3), and $1,005,972, including accrued interest of
$5,972 to repay the Company's line of credit (see Note 3). The remainder of the
proceeds will be used for general working capital purposes with respect to the
Company's ongoing licensing operations.

                                   (CONTINUED)

      Without a research and development department to provide ongoing
technological assistance and support to its licensees, all remaining deferred
revenue related to nonrefundable license fees (and any related withholding tax)
was recognized upon the transfer of the employees to the acquirer.

      The Company has granted the acquirer a security interest in its
intellectual property to secure certain obligations and warranties with respect
to the intellectual property for a period of six years following the effective
date of the Agreement. After the third year following the effective date of the
Agreement, the Company may terminate the security interest by depositing
$4,000,000 in an escrow account. Such amount is reduced by $1,000,000 in each of
the two succeeding years, and the escrow terminates the following year.

      Management believes that all of the license fee may not be realized due to
amounts that will have to be paid out of the escrow fund or amounts that will
have to be paid prior to the establishment of the escrow. Accordingly, the
Company plans to recognize $4,000,000 of the license fee ratably over the first
three years following the closing of the Agreement, which approximates the time
period during which the Company expects to be incurring costs to maintain its
patents in support of the license agreement. Subsequently, amounts will be
recognized as the escrow fund described above is reduced.

3. DEBT

      Obligations Under Capital Leases

      On July 18, 1996, in connection with the sale of assets to a component
manufacturer in the disk drive industry, all obligations under capital leases
were transferred to such manufacturer.

      Short-Term Borrowings

      At June 30, 1996, the Company had a line of credit with its primary bank
to provide short-term working capital of up to $1,000,000. The line of credit
bears a variable interest rate of prime plus 2.5% and is collateralized by the
assets of the Company. On July 18, 1996, the balance outstanding of $1,000,000
was repaid upon the closing of the Agreement.

      (see Note 2) ........................................    $2,450,000
</TABLE>

      On July 8, 1996, the Company received an additional $350,000 from a
promissory note issued to the acquirer. On July 18, 1996, the promissory notes
issued to the acquirer were partially offset against proceeds from the sale of
assets, with the remainder being forgiven (see Note 2). In addition, $597,787,
including accrued interest of $51,112, of the convertible promissory notes
issued to existing investors was repaid.

      Subordinated Debentures

      The Company's subordinated debentures at June 30 are summarized as
follows:

                                   (CONTINUED)

      On February 22, 1996, the subordinated debentures were modified such that
the Company was obligated to pay $2,000,000 against the outstanding accrued
interest by July 31, 1996. On July 18, 1996, upon closing the Agreement, this
amount was paid. Furthermore, if certain financial conditions are not met, the
debenture holder will forgive the remaining accrued interest and principal
balance on September 30, 1996, in return for 5% of the royalties the Company may
receive from its present and future licenses through the year 2001. The Company
does not anticipate meeting these conditions and therefore expects to recognize
a gain of approximately $12,700,000 in fiscal 1997 in connection with the
anticipated forgiveness of the accrued interest and principal.

      Cross Default Provisions

      The above subordinated debentures include certain cross default provisions
that provide for the debentures to be immediately due and payable if the Company
was to be declared in default with any of its other creditors.

4. COMMITMENTS

      In connection with the Agreement, the Company transferred its principal
facility to the acquirer who assumed the remaining lease payments. At that time,
the Company entered into a lease which expires in April 1999 for a smaller
office facility. A schedule of future minimum lease payments as of June 30, 1996
under the new lease agreement is as follows:

      The holders of Series A and B preferred stock are entitled to
noncumulative dividends, as declared by the Board of Directors out of legally
available funds, at a rate of $0.2124 and $0.25 per share, per annum,
respectively. After payment of the dividend preferences and payment to the
holders of common stock of noncumulative dividends, as declared by the Board of
Directors out of legally available funds, at a rate of $0.10 per share, per
annum, the preferred stock shall participate, as if converted on a
share-for-share basis with common stock, as to any dividends paid by the
Company. Such dividends are noncumulative.

      Series A and B preferred stock are convertible at any time after the date
of issuance into common stock on a one-for-one basis, subject to adjustment for
certain subsequent dilutive stock issuances. In addition, the Series A and B
preferred stock will automatically convert into common stock upon the closing of
an underwritten public offering of the Company's common stock at not less than
$4.00 per share, which results in gross proceeds of not less than $10,000,000,
or in the event of an affirmative vote of the holders of at least 51% of Series
A and B preferred stock, respectively.

                                   (CONTINUED)

      Upon liquidation, the Series B preferred shareholders are entitled to
receive an amount equal to $2.50 per share plus the aggregate amount of any
declared but unpaid dividends, after which the Series A preferred shareholders
are entitled to receive an amount equal to $2.124 per share plus the aggregate
amount of any declared but unpaid dividends. After the distributions above have
been made, remaining amounts shall be distributed among the holders of Series A
and B preferred stock and common stock pro rata, based on the number of shares
of common stock held by each shareholder, assuming conversion of all preferred
stock. Preferred shareholders participate in the voting rights of the Company as
if their shares were converted to common stock.

      Warrants to Purchase Preferred Stock

      At June 30, 1996, certain of the Company's lessors held warrants to
purchase 301,318 shares of the Company's Series B preferred stock, exercisable
at $2.50 per share through the later of September 2003 or five years after the
closing of a public offering of the Company's common stock. The Company
estimated the fair value of these warrants at $150,000. This amount is being
amortized over the life of the lease agreements.

      At June 30, 1996, the sales agent in connection with the sale of the
Series B preferred stock held warrants to purchase 687,000 shares of Series B
preferred stock, exercisable at $2.50 per share and expiring on March 23, 1998.
The warrants are convertible into warrants to purchase shares of common stock.
The Company estimated the fair value of these warrants to be approximately
$103,000.

      At June 30, 1996, the Company's primary bank held warrants to purchase
approximately 110,000 shares of the Company's preferred stock at the lower of
$2.50 or the share price of the next security issued by the Company, exercisable
from November 2000 through February 2001, respectively.

      Warrants to Purchase Common Stock

      At June 30, 1996, one of the Company's lessors held warrants to purchase
80,000 shares of the Company's common stock, exercisable at $2.50 per share
through the later of January 2005 or five years after the closing of a public
offering of the Company's common stock.

</TABLE>

      As of June 30, 1996, the Company had federal net operating loss and credit
carryforwards of approximately $98,000,000 and $3,300,000, respectively,
expiring in various years beginning in 1997 through 2010. The Company also has
state net operating loss and credit carryforwards of approximately $31,000,000
and $1,200,000, respectively. The state operating loss carryforwards will expire
in various years beginning in 1997 through 2001, while the credit carryforwards

                                   (CONTINUED)

      Tax law provides that the use of net operating loss and credit
carryforwards are limited if there is a substantial change in the ownership of
the Company. Due to prior years' equity transactions, such a change has
occurred. Approximately $75,000,000 of federal net operating loss and all credit
carryforwards are subject to an annual limitation. The annual limitation is
approximately $1,200,000 per year. The balance of $22,000,000 federal net
operating loss carryforwards can be used without limitation.
Similar limitations apply to state carryforwards.

      CRT has a federal net operating loss carryforward of approximately
$7,529,000.

Censtor the right, under certain conditions, to grant sublicenses to patents
owned by Denka.

        C.      Censtor has granted and is granting patent licenses to several
companies to manufacture and sell products. Licensee desires to obtain such a

<PAGE>   2

surface defining a plane, with the transducer having a loop of magnetic
material extending further in a direction parallel than perpendicular to the
plane, which device is unlike a flying head or a head which is designed to
react to airflow dynamics to ensure a nominal head-disk physical spacing during
operation; provided, however, that any head device which first becomes
available in significant commercial quantities after December 31, 2004 shall
not be considered a Censtor-Type Head.

including utility models and design patents, issued or issuing on patent
applications entitled to an effective filing date after the Effective Date but

        2.1  Grant.  Subject to the terms and conditions of this Agreement,
Censtor hereby grants to Licensee a worldwide, non-exclusive, non-transferable

Licensee hereby guarantees the performance by each such sublicensed Affiliated
Entity of all applicable obligations contained herein.

documentation relating to products offered for sale by Licensee or any of its
Affiliated Entities utilizing any Censtor Patents. A current list of Trademarks
is attached as Exhibit A hereto. If Licensee or any of its Affiliated Entities
elects to use the Trademarks, they shall use the Trademarks in accordance with
the instructions from Censtor and agree that Censtor may from time to time
revise these instructions. All representations of Censtor's Trademarks so used
shall be exact duplicates of those used by Censtor or shall first be submitted
to Censtor for approval of design, color, and other details.

     2.4  Limitations.

          (a)  No license or other right is granted, by implication, estoppel or
otherwise, to Licensee, under any Censtor Patents or other proprietary rights
now or hereafter owned or controlled by Censtor except for the licenses and
rights expressly granted in this Agreement.

          (b)  The scope of the license granted to Licensee under Section 2.1
does not include the right to manufacture and distribute or authorize customers
to use or distribute heads as separate components not incorporated in disk
drives or other data storage products, except as necessary for repair or spare
parts purposes in support of products previously sold, leased or otherwise
transferred by Licensee or any of its Affiliated Entities, and except that
Licensee and its Affiliated Entities may, to the extent not inconsistent with
Censtor's contractual obligations to its current licensees, liquidate excess
inventory through sales of heads to any Censtor licensee under its license from
Censtor or through sales of heads to others (provided that, in the case of such
sales of heads to others, the heads sold will be deemed to be Royalty Bearing
Products if covered by a then issued Censtor Patent and the royalty due on
account of such sales will be determined by the provisions of Section 4.2
hereof).

          (c)  The scope of the license granted to Licensee under Section 2.1
does not include the right to sell, lease or otherwise transfer media to
unaffiliated customers as separate components not incorporated in disk drives or
other data storage products, except as necessary for repair or spare parts
purposes in support of products previously sold, leased or otherwise
transferred, and except that Licensee and its Affiliated Entities may sell,
lease or



                                       3
<PAGE>   4
transfer media to unaffiliated customers who are Censtor licensees and to others
to the extent not inconsistent with Censtor's contractual obligations to its
current licensees.

          (d)  The provisions of this Section 2.4 are intended solely as limits
on the scope of the license granted under Section 2.1 hereof and shall not
operate or be construed as covenants under this Agreement. Consequently, any
assertion by Censtor that Licensee or any of its Affiliated Entities is
operating beyond the limits set forth in Section 2.4(b) or (c) hereof must be
made as a patent infringement claim independent of this Agreement and will not
be a breach of this Agreement regardless of the outcome of such claim.

     2.5  Purchase of Components from CRT.  Censtor shall promptly authorize
Contact Recordings Technology, Inc. and its successors and permitted assigns
("CRT"), its manufacturing licensee, to sell heads, head gimbal assemblies and
HSAs covered by Censtor Patents to or for Licensee and one or more of Licensee's
designated Affiliated Entities. Censtor shall not revoke such authorization
during the term of this Agreement.

3.  LICENSES FROM LICENSEE

     3.1  License to Censtor.  Licensee hereby grants to Censtor a paid-up,
royalty-free, worldwide, non-exclusive, non-transferable (except as described in
Section 9.4 below) license under the Licensee Improvement Patents to
manufacture, have manufactured, import, use, lease, sell and otherwise transfer
any product or process that has data storage applications and which is covered
by one or more claims in the Licensee Improvement Patents.

     3.2  Sublicense Rights.  Censtor shall have the right to grant sublicenses
of the rights granted in Section 3.1 above only to CRT and Denka.

4.  LICENSE FEE AND ROYALTIES

     4.1  License Fee.  As an initial, non-refundable license fee, Licensee
hereby assigns to Censtor without recourse all of Licensee's interest in that
certain Convertible Promissory Note in the principal amount of ********** made
by CRT dated September 25, 1995, as amended (originally issued to a subsidiary
of Licensee and subsequently assigned to Licensee).

     4.2  Royalties.

          (a)  Censtor shall be entitled to the following royalties (without
duplication) on the sale, lease or other transfer for value of each Royalty
Bearing Product by Licensee and its Affiliated Entities to an unaffiliated
customer.

             (i)  if the Royalty Bearing Product contains only Censtor-Type
        Heads, the royalty shall be equal to **************** of the amount by
        which the HSA Cost of a comparably performing HSA which does not use
        Censtor-Type Heads exceeds the actual HSA Cost of the Royalty Bearing
        Product, provided that if such excess is (A) less than *********** per
        head, the royalty shall be *********** per head for each Censtor-Type
        Head in the Royalty Bearing Product, or


*Omitted and filed separately with the
 SEC pursuant to a confidential 
 treatment request.
                                       4
<PAGE>   5
        (B) more than *********** per head, then the royalty shall be
        ********** per head for each Censtor-Type Head in the Royalty Bearing
        Product;

                 (ii)  If the Royalty Bearing Product contains one or more heads
        which are covered by a then issued Censtor Patent but does not contain
        any Censtor-Type Heads, the royalty shall be *********** per head for
        each head in the Royalty Bearing Product which is covered by a then
        issued Censtor Patent, provided that no royalty shall accrue or be
        payable in respect of any such sale, lease or other transfer for value
        which occurs on or before December 31, 1997;

                 (iii)  if the Royalty Bearing Product contains both (A) a
        Censtor-Type Head and (B) a head which is not a Censtor-Type Head but is
        covered by a then issued Censtor Patent, then the royalty shall be
        calculated on a per head basis with Section 4(a)(i) hereof applying to
        the Censtor-Type Heads in such Royalty Bearing Product and Section
        4(a)(ii) hereof (including the moratorium contained therein) applying to
        the heads which are not Censtor-Type Heads but which are covered by a
        then issued Censtor Patent (provided such combined royalty shall not
        exceed maximum royalty which would have been payable if all heads in
        such Royalty Bearing Product which are covered by a then issued Censtor
        Patent were Censtor-Type Heads); and

                (iv)   if the Royalty Bearing Product does not contain a head
        covered by a then issued Censtor Patent (but is nevertheless a Royalty
        Bearing Product), Censtor and Licensee shall negotiate in good faith a
        reasonable royalty not to exceed the royalty that would be payable under
        Section 4.2(a)(ii) above and subject to the moratorium contained
        therein;

provided, however, that no royalties shall accrue or be payable in respect of
Royalty Bearing Products which contain heads purchased by Licensee or one or
more of its Affiliated Entities (or their designated assembly vendor) from CRT
and provided further that no royalties shall accrue or be payable in respect of
Royalty Bearing Products on account of the inclusion therein of components
procured by Licensee or one or more of its Affiliated Entities (or their
designated assembly vendor) from Read-Rite Corporation, its successors and
assigns ("RRC") to the extent Censtor has licensed RRC to manufacture, have
manufactured, import, use and sell such components.

          (b)  Upon payment by Licensee and its Affiliated Entities of an
aggregate of ********* in royalties attributable to Censtor-Type Heads in
Royalty Bearing Products, the royalty obligation attributable to Censtor-Type
Heads in Royalty Bearing Products shall cease.

          (c)  Upon payment by Licensee and its Affiliated Entities of an
aggregate of ********* in royalties pursuant to Section 4.2(a)(ii), 4.2(a)(iii)
(insofar as it relates to heads which are not Censtor-Type Heads) and 4.2(a)(iv)
hereof, the royalty obligation attributable to sales of such Royalty Bearing
Products shall cease.



*Omitted and filed separately with the
 SEC pursuant to a confidential 
 treatment request.                
                                       5
<PAGE>   6
        (d)  The ******** maximum aggregate royalty payable in respect of sales
of Royalty Bearing Products which contain Censtor-Type Heads shall be reduced to
********, and the royalty obligation payable in respect of Royalty Bearing
Products which contain Non-Censtor-Type Heads will be eliminated, upon the
occurrence of either of the following events (without placing any obligation on
Licensee to accomplish either event): (i) Licensee is the first customer to
purchase ******** heads from CRT or (ii) Licensee has loaned CRT or Censtor more
than ******** by April 1, 1996 with repayment terms providing for repayment of
the loan without interest by way of a discount equal to or corresponding to
**************** per head gimbal assembly purchased from CRT by Licensee and its
Affiliated Entities.

        (e)  The maximum royalty provisions of Section 4.2(b) and (c), as
adjusted by Section 4.2(d), if and when applicable, do not apply to the sale,
lease or transfer for value of a Royalty Bearing Product which is covered by a
Censtor Patent that issues on a patent application entitled to an effective
filing date on or after October 1, 1995 which differs from the prior art on the
basis of (i) the structure of a Censtor-Type Head which includes a
magnetoresistive element or (ii) any other major new development by Censtor in
(x) the structure of a magnetoresistive head or (y) some other type of
component or technology not currently used by Licensee or any of its Affiliated
Entities in disk drives. In such event, Censtor shall, upon request by Licensee
at any time thereafter, negotiate in good faith such reasonable additional
terms (including without limitation royalty rate and maximum aggregate royalty)
as are reasonably necessary to prevent Licensee from operating at a competitive
disadvantage attributable to the royalty obligations of this Agreement.

        (f)  Notwithstanding anything in this Agreement to the contrary,
Censtor expressly acknowledges and agrees that Licensee shall at all times have
the right to challenge the validity, enforceability and asserted scope of any
Censtor Patent, and Licensee's royalty obligations are applicable only to
products which are covered by valid and enforceable patent rights.

        (g)  Censtor hereby releases and discharges Licensee and its Affiliated
Entities from any liability for infringement of any Censtor Patents or other
intellectual property rights of Censtor with respect to sales of products by
Licensee or any of its Affiliated Entities occurring prior to the Effective
Date. 

    4.3  Payments and Accounting.

        (a)  Records and Audits.  With respect to the number of Royalty Bearing
Products sold, leased or otherwise transferred for value by Licensee and its
Affiliated Entities and the royalties payable under the provisions of Section
4.2, Licensee shall keep complete and accurate records. These records shall be
retained for a period of three (3) years from the date of payment,
notwithstanding the expiration or other termination of this Agreement. Censtor
shall have the right to examine and audit, through an independent accounting
firm, acceptable to Licensee, not more than once a year, and during normal
business hours, all such records and such other records and accounts as may
contain, under recognized accounting practices, information bearing upon the
amount of royalties payable to Censtor under this 


*Omitted and filed separately with the
 SEC pursuant to a confidential 
 treatment request.
                                       6

Agreement. Prompt adjustment shall be made by Licensee to compensate for any
errors and/or omissions disclosed by such examination or audit which result in
an underpayment of royalties hereunder. Should the amount of any such error
and/or omission exceed of five percent (5%) of the total royalties due for the
period under audit, then upon request by Censtor, Licensee shall pay for the
reasonable cost of the audit.

                (b)  Reports and Payment Terms.  Within forty-five (45) days
after the end of each of the first three fiscal quarters of Licensee and within
ninety (90) days after the end of each of its fiscal years, until all royalties
payable hereunder shall have been reported and paid, Licensee shall furnish to
Censtor a statement in suitable form showing all Royalty Bearing Products sold
by Licensee and its Affiliated Entities during such quarter and the amount of
royalty payable thereon. If no products subject to royalty have been sold, that
fact shall be shown on such statement. Also, within such thirty (30) day period
Licensee shall pay to Censtor the royalties payable under Section 4.2 for such
quarter. All royalty and other payments to Censtor hereunder shall be in United
States dollars.

5.      CONFIDENTIAL INFORMATION

        5.  Definition.  As used in this agreement, the term "Confidential
Information" shall mean any information disclosed pursuant to this Agreement by
one party to the other during the term of this Agreement which is in written,
graphic, machine readable or other tangible form and is marked "Confidential,"
"Proprietary" or in some other manner to indicate its confidential nature.
Confidential Information may also include oral information disclosed by one
party to the other in the course of the performance of this Agreement, provided
that such information is designated as confidential at the time of disclosure
and reduced to a written summary by the disclosing party, within thirty (30)
days after its oral disclosure, which is marked in a manner to indicate its
confidential nature and delivered to the receiving party. As used herein,
"Confidential Information" may include, without limitation, the know-how,
inventions, prototypes, materials, processes, process equipment, designs,
specifications, and certain technical data, business and financial data, product
information, patent applications, and documents relating to the development,
manufacturing, testing, and marketing of products disclosed by either party to
the other directly in writing or by drawings or inspection of parts or
equipment.

        5.2  Nondisclosure.  Each party shall treat as strictly confidential
all Confidential Information of the other party, shall implement reasonable
procedures to prohibit the disclosure, unauthorized duplication, misuse or
removal of the other party's Confidential Information and shall not disclose
such Confidential Information to any third party except as may be necessary and
required in connection with the rights and obligations of such other party
under this Agreement, and subject to confidentiality obligations at least as
protective as those set forth herein. Without limiting the foregoing, each of
the parties shall use at least the same procedures and degree of care which it
uses to prevent the disclosure of its own confidential information of like
importance to prevent the disclosure of Confidential Information disclosed to
it by the other party under this Agreement.


                                       7
<PAGE>   8
        5.3     Exceptions. Notwithstanding the above, neither party shall have
liability to the other with regard to any Confidential Information of the other 
which:

                (a)     was generally known and available in the public domain
at the time it was disclosed or becomes generally known and available in the
public domain through no fault of the receiver;

                (b)     was known to the receiver without restriction at the
time of disclosure as shown by the files of the receiver in existence at the
time of disclosure and was not acquired directly or indirectly from a third
party under obligation of confidentiality to the disclosing party;

                (c)     is disclosed with the prior written approval of the 
disclosure;

                (d)     was independently developed by the receiver without any
use of the Confidential Information, provided that the receiver can demonstrate
such independent development by documented evidence prepared contemporaneously
with such independent development;

                (e)     becomes known to the receiver without restriction from
a source other than the discloser without breach of this Agreement by the
receiver and otherwise not in violation of the discloser's rights; or

                (f)     is disclosed pursuant to the order or requirement of a
court, administrative agency, or other governmental body; provided, that the
receiver shall provide prompt, advance notice thereof to enable the discloser
to seek a protective order or otherwise prevent such disclosure.

        5.4     Binding Other Parties. Each party shall obtain the execution of
proprietary nondisclosure agreements with its subsidiaries, employees, agents
and consultants having access to Confidential Information of the other party,
and shall diligently enforce such agreements, and shall exercise due care to
control the actions of such subsidiaries, employees, agents and consultants in
this respect so long as they have a working relationship with the party.

        5.5     Rights Under Breach. Each party acknowledges that the other
party's Confidential Information is an extremely valuable business asset, the
misuse or improper disclosure of which would cause irreparable harm to the
interest of such party. Accordingly, if either party breaches any of its
obligations under this Section the other party shall be entitled to equitable
relief to protect its interest therein, including but not limited to injunctive
relief, as well as money damages. In addition, the parties agree upon request
to cooperate in efforts seeking to enjoin the subsequent wrongful disclosure of
Confidential Information by third parties to whom such information was
disclosed by a receiving party hereunder.

        6.1  Censtor Ownership.  During the term of this Agreement, Censtor
warrants that it either (a) owns all right, title and interest in or (b) has
the right to license to Licensee the Censtor Patents. Licensee acknowledges
that Censtor has made no representation to Licensee with respect to patent
prosecution efforts other than to maintain until July 31, 1997 a patent

portfolio which is consistent, in Censtor's good faith judgment, with good
business practices.

        6.2  Licensee Ownership.  Licensee shall be free to develop
Improvements and Licensee shall own, subject to Section 3, all right, title and
interest in such Improvements. To the extent such Improvements embody Censtor

expire Censtor Patent, whichever occurs later.

        8.2  Termination.

            (a)  If either party defaults in the performance of any material
obligation hereunder and if such default is not corrected within thirty (30)

non-defaulting party, then the non-defaulting party, at its option, may, in
addition to any other remedies it may have, terminate this Agreement.

           (b)  Either party may terminate this Agreement effective upon
written notice to the other party in the event that the other party becomes the
subject of a voluntary or involuntary petition in bankruptcy or any proceeding
relating to insolvency, or composition for the benefit of creditors, if that
petition or proceeding is not dismissed within sixty (60) days after filing.

        8.3  Effect of Termination.

           (a) Except as otherwise expressly stated herein, upon any
termination or expiration of this Agreement, all licenses and rights granted by
the parties to each other hereunder shall terminate, and neither Licensee nor
any of its Affiliated Entities shall have any rights with respect to any
Censtor Patents. The provisions of Sections 5, 7, 8, and 9 shall survive any
termination or expiration of this Agreement for any reason. The provisions of
Section 3.2 shall survive any termination of this Agreement but shall not
include any Licensee Improvement Patent which issues after the effective date

                              ASSIGNMENT OF LEASE
                           AND CONSENT TO ASSIGNMENT

        THIS ASSIGNMENT OF LEASE AND CONSENT TO ASSIGNMENT (this "Assignment")
is made and entered into effective as of this 2nd day of July, 1996, by and
among The Sobrato Group, a California Limited Partnership ("Landlord"), whose
address is 10600 N. De Anza Blvd., Suite 200, Cupertino, CA 95014, Censtor
Corporation, a California corporation ("Assignor"), whose address is 2105
Hamilton Avenue, Suite 270, San Jose, CA 95125, and Read-Rite Corporation, a
Delaware Corporation ("Assignee"), whose address is 345 Los Coches Street,
Milpitas, CA 95035, who agree as follows.

        1. Recitals. This Assignment is made with reference to the following
facts and objectives:

           a. Landlord and Assignor, as tenant, entered into a written Lease
dated November 28, 1983 ("the Lease"), in which Landlord leased to Assignor
and Assignor leased from Landlord premises located in the City of San Jose,
County of Santa Clara, California, as more particularly described in the Lease
("Premises"). A copy of the Lease and all amendments thereto is attached
hereto as Exhibit "A" and incorporated herein by this reference.

           b. Assignor now desires to assign all its right, title, and interest
in the Lease to Assignee.

           c. Landlord shall consent to the proposed assignment on the
conditions set forth in this Assignment.

        2. Effective date of assignment: The assignment of the Lease shall take
effect on July 2, 1996, and Assignor shall give possession of the Premises to
Assignee on that date.

        3. Assignment and assumption: Assignor assigns and transfers to
Assignee all its right, title, and interest in the Lease, and Assignee accepts
the assignment and assigns and agrees to perform, as a direct obligation to
Landlord, all the obligations of "Lessee" under the Lease arising under the
Lease from and after the effective date of this Assignment.
<PAGE>   2
        4. Landlord's consent: Landlord consents to the assignment without
waiver of the restriction concerning further assignment.

        5. Tenant Improvements: Neither Landlord nor Assignor has agreed to
perform or install any tenant improvements for the benefit of Assignee.

        6. Assignor's liability: Assignor shall remain liable for the
performance of the provisions of the Lease.

        7. Assignor's and Landlord's Estoppel: Assignor and Landlord hereby
certify to the best of their knowledge the following facts:

           a. The copy of the Lease attached as Exhibit "A" is a true and
complete copy of the Lease, including all modifications and amendments thereto.

           b. The term of the Lease commenced on June 1, 1984 and will expire
on July 31, 1998. The Lease contains one three-year option to extend the term
which has not been exercised and which is subject to all other terms and
conditions of Section 28 of the Lease.

           c. The base rent under the Lease is $37,836.60 per month through
July 31, 1996; $39,828.00 per month from August 1, 1996 through July 31, 1997;
and $41,819.40 per month from August 1, 1997 through July 31, 1998. Assignor is
current in its payment obligation respecting rent and any other required
payments. 

           d. Neither Landlord nor Assignor is in default under any provision
of the Lease, nor is there any condition which, through the passage of time or
otherwise, would constitute a default under the Lease.

           e. Assignor and Landlord acknowledge that Assignee may rely upon the
representations contained in this Section 7 in entering into and accepting
assignment of the Lease.

        8. Assignee to hold Assignor harmless: If Assignee defaults under the
Lease, Assignee shall indemnify and hold Assignor harmless from all damages
resulting from the default. If Assignee defaults in its obligations under the
Lease and Assignor pays rent to Landlord or fulfills any of Assignee's other
obligations in order to prevent Assignee from being in default, Assignee
immediately shall reimburse Assignor for the amount of rent or costs incurred
by 
<PAGE>   3
Assignor in fulfilling Assignee's obligations under this Assignment, together
with interest on those sums at the rate of 10% per annum. Notwithstanding the
foregoing, however, Assignee shall have no liability to Assignor with respect
to any defaults or other matters under the Lease which are attributable to acts
or omissions of Assignee prior to the effective date of the Assignment.

        9. Default of Lease: Notice to Assignor:

           a. Notice to Assignor: Landlord will send to Assignor any notice of
default that Landlord sends to Assignee.

           b. Assignor's remedies against Assignee. If Assignee defaults under
the Lease, Assignor shall have all rights against Assignee that are available
by law and those contained in the Lease, including, without limitation,
Assignor's right to reenter and retake possession of the Premises from Assignee.

       10. Security deposit: The parties acknowledge that Landlord now holds
the sum of thirty-six thousand, eight hundred and forty-one dollars
($36,841.00) as a security deposit, to be applied subject to the provisions of
the Lease. Assignor releases all claims to that sum, and the sum shall be held
by Landlord for the benefit of Assignee, subject to the provisions of the Lease.

       11. Amendment of Lease: Landlord and Assignee shall not enter into any
agreement that amends the Lease without Assignor's consent. Any amendment of
the Lease in violation of this provisions shall have no force or effect on

        technology and know-how (i) owned by Censtor as of the Effective Date,
        (ii) developed by Censtor on or prior to the Effective Date, or (iii)
        licensed to Censtor from a third party licensor as of the Effective Date
        which Censtor has a right to license to RRC without additional payments
        or other obligations to such third party licensor, provided that Censtor
        shall sublicense the technology to RRC that requires such additional
        payments or obligations to the extent it may be sublicensed if RRC
        elects to make such additional payments or assume such other
        obligations. "Technology" shall include without limitation, technical
        information, know-how, negative know-how, trade secrets, processes,
        procedures, compositions, devices, methods, formulas, protocols,
        techniques, designs, drawings, mask works, or data.

        1.4  "Intellectual Property Rights" means, collectively, the Patents,
        Technology and Software and all current and future worldwide patents,
        trade secrets, copyrights, copyright registrations and applications
        therefor, moral rights, and all other intellectual property rights and
        proprietary rights arising under the Patents, Technology or Software,
        whether arising under the laws of the United States or any other state,
        country or jurisdiction, excluding any trademarks or servicemarks.

        1.5  "Affiliate" shall mean a company that is controlled by,
        controlling, or in common control with a party hereto. Control shall
        mean that more than fifty percent (50%) of the stock entitled to vote
        for the election of directors is directly owned by a party hereto, but
        only so long as such ownership exists. An "RRC Affiliate" shall
        include, but not be limited to, Read-Rite International.

II.     GRANT

        2.1  Grant.  Censtor grants to RRC a worldwide, perpetual, royalty-free,
        fully-paid up, non-exclusive license, including the right to sublicense
        to RRC Affiliates, under the Intellectual Property Rights to make, have
        made, use, sell, offer for sale, import, export, display, modify, and
        distribute any products, create derivative works, practice any method,
        process, or procedure, and otherwise exploit the Patents, Technology or
        Software. The license granted under this Section 2.1 shall be revocable
        solely in the event that RRC fails to make the Final Payment referenced
        in the Asset Purchase Agreement on the Final Payment Date defined
        therein, net of any amounts withheld as security for claims under
        Section 8 thereof. Upon RRC's payment to Censtor of such Final Payment,
        the licenses granted hereunder shall become irrevocable, notwithstanding
        any withholding by RRC of a portion of such Final Payment pursuant to
        Section 8.2 of the Asset Purchase Agreement.

        2.2  Delivery.  Censtor has delivered to RRC copies of all the Patents,
        Technology and Software as of the Effective Date, which copies shall be
        the property of RRC.

        2.3  Security Interest.  23.1  Grant.  RRC hereby retains and Censtor
        hereby grants to RRC a security interest in the Intellectual Property
        Rights licensed hereunder to RRC to secure Censtor's obligations under
        Sections 2.4, 3.1 or 3.2 of this Agreement (the "Secured Obligations")
        for the period commencing on the Effective Date and terminating


                                       2

<PAGE>   3
on the sixth anniversary of the Effective Date (the "Termination Date"). Censor
agrees to promptly execute documents requested by RRC to perfect and protect
such security interest at the Effective Date.

2.3.2. Termination of Security Interest; Escrow. Censtor may terminate the
security interest created hereunder on the third (3rd) anniversary of the
Effective Date by depositing an amount (the "Escrow Amount") that is the
greater of (i) four million dollars ($4,000,000) or (ii) the full amount of any
claim or claims asserted in writing by RRC against Censtor for breach of any
Secured Obligations (a "Secured Obligation Claim") on or prior to such
anniversary in cash into an escrow account established pursuant to a mutually
agreeable escrow agreement. Said escrow agreement shall provide for a release
of all or a portion of the Escrow Amount to RRC to satisfy claims by RRC
against Censtor hereunder relating to any breach of the Secured Obligations.
Thereafter, Censtor may reduce the Escrow Amount by one million dollars
($1,000,000) on each of the fourth (4th) and fifth (5th) anniversaries of the
Effective Date, respectively, provided, however, that any such reduction shall
not cause the funds remaining in the escrow to be less than the amount of any
Secured Obligation Claim or Claims by RRC outstanding on such anniversaries. If
RRC has an outstanding Secured Obligation Claim at the Termination Date then
(i) if Censtor has not terminated the security interest by depositing the
Escrow Amount, the security interest shall survive until the claims are finally
resolved unless Censtor deposits cash in the full amount of such claim in an
escrow account to secure such claims, or (ii) if Censtor has terminated the
security interest, the escrow shall survive the Termination Date until such
claims are finally resolved.

2.3.3. Senior Security Interest: Subordination. Censtor represents and warrants
that the security interest granted herein is senior to any other security
interest granted in the Patents, Software or Technology. Censtor shall not
grant, issue, or convey security interests to which the security interest
granted herein would be subordinate, except (i) any security interest granted
for money borrowed, provided that the amount borrowed shall not exceed two
million dollars ($2,000,000) at any time, and any such obligation to repay
money shall be a Secured Obligation hereunder, and RRC shall have the option to
repay on Censtor's behalf such borrowings at any time and to add the amount of
such repayments to any amounts due upon exercise of the security interest, and
(ii) RRC acknowledges that Denki Kagaku Kogyo Kabushiki Kaisha ("Denka") holds
a security interest in certain Censtor Patents. To address said security
interest, concurrently herewith Censtor has delivered to Censtor's counsel such
sums as are required to satisfy any obligations of Censtor to Denka necessary
to obtain a release of said security interest (the "Satisfaction Payment"), and
caused to be delivered by Denka to Censtor's counsel a fully executed,
irrevocable release of said security interest (the "Release"). Censtor
covenants that, on or before July 31, 1996, it will cause its counsel to
simultaneously deliver the Satisfaction Payment to Denka, and the Release to
RRC. RRC hereby agrees that the security interest granted hereunder is and will
be subject to (i) any license granted by Censtor in the Intellectual Property
Rights, including licenses granted after the date of this Agreement, and (ii)
any security interest to secure obligations for money borrowed as provided
above, including any such security interest granted after the date of this
Agreement. RRC hereby agrees to promptly execute documents reasonably requested
by 


                                       3

<PAGE>   4
        Censtor to acknowledge release of the security interest at the
        Termination Date (or such later date as provided above) and to
        acknowledge the subordination of its security interest for money
        borrowed granted by Censtor as provided above. 

        2.4     Most Favored Licensee.  If Censtor licenses the Intellectual
        Property Rights to any person, firm or corporation under more favorable
        terms and conditions than those granted to RRC, it shall provide RRC the
        benefit of those terms and conditions effective upon the date of
        execution of the more favorable license. For the purposes of determining
        whether a license is more favorable than the present Agreement under
        this  Section 2.4, the parties agree to consider each transaction as a
        whole. The parties agree that should Censtor enter into a new components
        supply license, it shall deliver to RRC an initial summary of the terms
        of such license. RRC shall have fifteen (15) days following receipt of
        such summary to elect to retain RRC's existing license per the terms set
        forth herein, or to elect on a preliminary basis to accept the terms of
        said new license. In the latter event, Censtor shall prepare and submit
        for RRC's review a draft license agreement, together with a signed
        certificate of an officer of Censtor stating that said license
        agreement is the same as the new components supply license in all
        material respects. RRC shall thereafter have fifteen (15) additional
        days to make its final election to accept or reject said new proposed
        license. In addition, Censtor shall not grant rights in the Intellectual
        Property Rights to any disk drive manufacturer under terms and
        conditions more favorable than those granted by Censtor to Western
        Digital Corporation ("WDC") or Maxtor Corporation ("MC"), respectively,
        without offering such terms to WDC and MC; provided, however, that
        Censtor shall not be required to (i) compare any terms granted to either
        WDC or MC to those granted to the other, or (ii) offer license terms to
        WDC or MC if at any time following the Effective Date WDC or MC, as the
        case may be, ceases to be a licensee of Censtor. If Censtor is required
        by this Section to offer license terms to either WDC or MC, Censtor
        shall offer such terms pursuant to procedures specified in its licenses
        with WDC or MC to the extent such procedures exist and, to the extent
        they do not, pursuant to the procedures specified above for offering
        license terms to RRC. 

        2.5     Limitations.  No license or other right is granted, by
        implication, estoppel or otherwise, to RRC or any other third parties
        except for the licenses and rights expressly granted in this Agreement. 


III.    REPRESENTATIONS, WARRANTIES AND INDEMNIFICATION.

        3.1     Representations and Warranties. As of the Effective Date of this
        Agreement, Censtor represents and warrants that, except as set forth in
        Schedule 3.1 hereto, (i) Censtor has the right and authority to enter
        into this Agreement and to grant the rights and licenses set forth
        herein; (ii) to Censtor's best knowledge the use of the Intellectual
        Property Rights in connection with Censtor's business operations in the
        ordinary course prior to the Effective Date does not constitute a direct
        infringement of the intellectual property rights of any other person,
        (iii) Censtor, to its best knowledge is not aware of any express
        challenge to, or any facts or circumstances that, on their face,
        constitute the basis for a challenge to, the validity, scope,
        enforceability, ownership or inventorship of the 

                                       4
<PAGE>   5
         Intellectual Property Rights; (iv) Censtor has not received any notice
         or other communication alleging that the manufacture, sale or use of
         products incorporating the Patents, Software or Technology infringe the
         intellectual property rights of any third party or violate any other
         third party rights; (v) Censtor has not granted any rights in the
         Patents, Software and Technology to any third party that are
         inconsistent with the rights and licenses granted to RRC by this
         Agreement, and (vi) Censtor has delivered to RRC all of the Patents,
         Technology and Software.

         3.2  Covenants.  Censtor covenants (i) that it will not grant any
         rights in the Patents, Software or Technology to any third party that
         conflict with the rights and licenses granted to RRC by this Agreement;
         and (ii) that as of the Effective Date of this Agreement there are no
         circumstances other than RRC's breach of this Agreement or patent
         expiration whereby the rights and licenses granted hereunder would be
         materially diminished, or have the effect of materially diminishing
         such rights and licenses. RRC may, upon breach of this Section,
         exercise its security interests under Section 2.2 above and the right
         to seek indemnification under Section 3.4 below.

         3.3  RRC Representations and Warranties.  As of the Effective Date of
         this Agreement, RRC represents and warrants that RRC has the right and
         authority to enter into this Agreement.

         3.4  Indemnification.  As the sole remedy for a material breach of a
         party's obligations under this Section 3, each party (as indemnitor)
         agrees to defend, indemnify, and hold the other party (as indemnitee),
         its Affiliates, shareholders, employees and agents harmless against any
         loss, liability, and expense (including reasonable attorneys' fees)
         arising from such material breach except in the case of RRC, RRC may
         also exercise the remedies provided by Section 7.2. The indemnitor
         shall have no obligation to indemnify the indemnitee under this section
         unless the indemnitee provides the indemnitor with (i) prompt written
         notice of such claim or action, (ii) control and authority over the
         defense or settlement of such claim or action, and (iii) proper and
         full information and reasonable assistance to defend and/or settle such
         claim or action.

         3.5  Disclaimer.  EXCEPT AS EXPRESSLY WARRANTED IN SECTION 3.1 ABOVE,
         (I) CENSTOR'S PATENTS, SOFTWARE, TECHNOLOGY AND INTELLECTUAL PROPERTY
         RIGHTS ARE PROVIDED TO RRC "AS IS" WITHOUT WARRANTY OF ANY KIND, (II)
         THE ENTIRE RISK AS TO THE RESULTS AND PERFORMANCE OF ANY HARDWARE OR
         SOFTWARE IS ASSUMED BY THE RECEIVING PARTY; AND (III) CENSTOR DISCLAIMS
         ALL WARRANTIES, EITHER EXPRESS OR IMPLIED, WITH RESPECT TO ITS
         DELIVERABLES, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF
         MERCHANTABILITY, NON-INFRINGEMENT AND FITNESS FOR A PARTICULAR PURPOSE.
         IN NO EVENT SHALL CENSTOR BE LIABLE FOR COST OF PROCUREMENT OF
         SUBSTITUTE PRODUCTS, SERVICES, OR TECHNOLOGY. THESE LIMITATIONS SHALL
         APPLY NOTWITHSTANDING ANY FAILURE OF ESSENTIAL PURPOSE OF ANY LIMITED
         REMEDY.

IV.     CONFIDENTIAL INFORMATION

        4.1  General.  The parties may, from time to time, in connection with
        this Agreement, disclose to each other Confidential Information.
        "Confidential Information" shall mean any information disclosed in
        writing by a party to this Agreement to any of the other parties to this
        Agreement, and marked by the disclosing party with the legend
        "CONFIDENTIAL" or other similar legend sufficient to identify such
        information as confidential proprietary information of the disclosing
        party. Confidential Information shall include the terms and conditions
        of this Agreement, but either party may disclose the existence and
        purpose of this Agreement as recited in the Background section. Neither
        party shall use any Confidential Information of the other party except
        as expressly authorized under this Agreement, and each party will use
        best efforts to prevent the disclosure of the other party's Confidential
        Information to third parties; provided that the parties may disclose
        Confidential Information, with similar protections in place, to the
        extent reasonably necessary to exploit the rights and license granted to
        such party hereunder (including the rights to grant and authorize
        sublicenses); and provided further that the recipient party's
        obligations under this Section 4 shall not apply to Confidential
        Information that:

                4.1.1 is disclosed orally without express designation as
                      Confidential Information; provided, however, that the
                      recipient party's obligations under this Section 4
                      shall apply to information disclosed orally if such
                      information is confirmed in writing as "CONFIDENTIAL"
                      by the disclosing party within thirty (30) days after
                      disclosure thereof;

                4.1.2 is in the recipient party's possession at the time of
                      disclosure thereof;

                4.1.3 is or later becomes part of the public domain through
                      no fault of the recipient party;

                4.1.4 is received from a third party having no obligations of
                      confidentiality to the disclosing party;

                4.1.5 is developed independently by the recipient party without
                      reliance upon or use of the disclosing party's
                      Confidential Information; or

                4.1.6 is required by law or regulation to be disclosed;
                      provided, however, that the party subject to such
                      disclosure requirement has provided written notice to
                      the other party promptly to enable such other party to
                      seek a protective order or otherwise prevent disclosure
                      of such Confidential Information.

        The parties agree to terminate on the Effective Date, all prior
        confidentiality and nondisclosure agreements between the parties
        including the Bilateral Non-Disclosure Agreement dated January 11, 1996;
        provided, however, that disclosures of Confidential


                                       6

<PAGE>   7
        Information made prior to the Effective Date shall continue to be
        governed by the terms of the applicable confidentiality or
        nondisclosure agreement.

V.      PATENTS AND INVENTIONS

        5.1     Disclosure of Inventions. Censtor will promptly disclose to RRC
        in writing any invention conceived of or reduced to practice by Censtor,
        its employees, contractors, or agents, alone or jointly with others, as
        of the Effective Date of the Agreement. Censtor shall release its
        employees from any confidentiality obligations to the extent such
        obligations prohibit the disclosure of Censtor Confidential Information
        to RRC; provided, however, that nothing in this Agreement shall require
        Censtor, or its employees, contractors, or agents, to disclose
        Confidential Information of any third party unless Censtor is authorized
        to do so by license or agreement with such third party.

        5.2     Applications. Censtor shall file patent applications based on
        the Patents and maintain the Patents during the term of this Agreement.
        During the term of this Agreement, Censtor shall provide RRC with a
        report once per month containing a list of patent applications based on
        the patents that Censtor elects to abandon, or Patents for which Censtor
        elects not to pay any fee required to maintain such Patent. Censtor
        shall consider any request by RRC to file or continue the prosecution of
        applications for Patents. If Censtor elects not to file or continue the
        prosecution of an application requested by RRC, RRC may request
        Censtor's consent to pursue and have assigned to RRC such draft patent
        application or patent application, which consent may be withheld only if
        Censtor determines that the coverage of such draft patent application or
        application is substantially covered by another application that is
        being pursued by Censtor. If consent is granted and RRC files or
        continues the prosecution application, RRC shall pay for the costs,
        including reasonable attorney's fees and related filing and maintenance
        costs, and RRC agrees to license Censtor on a world-wide, royalty-free,
        fully paid, irrevocable, non-exclusive basis with a right of sublicense
        to Patents issuing on such applications, provided Censtor pays one-half
        of the legal fees and costs incurred by RRC for such Patents.

VI. INFRINGEMENT

        6.1     Notice of Infringement. If RRC learns of any infringement of
        Censtor's Intellectual Property Rights, RRC shall so inform Censtor in
        writing and shall provide Censtor with reasonable evidence of the
        infringement.

        6.2     Legal Action.   RRC may request that Censtor take legal action
        against an alleged infringement of the Intellectual Property Rights. If
        Censtor initiates such action at RRC's request, it shall do so at its
        sole expense and RRC shall render all reasonable assistance that may be
        required by Censtor for such action. RRC shall not make any claim for
        damages recovered by Censtor. If Censtor does not initiate the legal
        action requested by RRC, RRC may request Censtor to consent to RRC
        initiating such action in Censtor's

                                       7
<PAGE>   8
        name. If Censtor consents to such representation, RRC may initiate such
        action at its sole expense and shall be entitled to take all necessary
        steps in the name of Censtor. Censtor shall render all reasonable
        assistance that may be required by RRC for such action and Censtor shall
        not make any claim for damages recovered by RRC.

        If Censtor does not consent to RRC commencing such action, then upon the
        request of RRC the following representatives of RRC and Censtor shall
        meet within ten (10) days after the date of the Censtor decision to
        attempt to resolve the matter: the General Counsel of RRC and the
        President of Censtor. If the matter has not been resolved within twenty
        (20) days of their first meeting, the parties shall attempt in good
        faith to resolve the controversy or claim in accordance with the
        Mediation Service of the Santa Clara County Bar Association. 

        6.3  Cooperation.  Each party shall cooperate with the other in
        litigation proceedings instituted under this Agreement (including
        without limitation by joining as a nominal party), but at the expense of
        the party by whom suit is brought. The party bringing the suit will
        control that litigation, except that the other party may elect to be
        represented at its own expense by counsel of its choice. Upon the
        request and at the expense of the requesting party, the other party
        shall make available at reasonable times and under appropriate
        conditions all relevant personnel, records, papers, information,
        samples, specimens and other similar materials in its possession.

        6.4  Attorneys' Fees.  Except as set forth in Section 3
        (Indemnification), each party shall bear its own attorney's fees and
        costs in connection with any dispute between the parties arising under
        this Agreement.


VII.  TERM AND REMEDIES

        7.1. Term.  This Agreement shall be perpetual.

        7.2  Remedies for Breach.  If Censtor is in material default of any
        provision of this Agreement other than the Secured Obligations, and such
        material default is not corrected within thirty (30) day of receipt of
        written notice of such default from RRC, RRC may pursue its available
        remedies in law or equity. If Censtor is in material default of the
        Secured Obligations, and such material default is not corrected within
        thirty (30) days of receipt of written notice of such material default,
        RRC shall first pursue a remedy of monetary damages or injunctive relief
        pursuant to Section 3.4. If RRC does not receive full and complete
        payment or settlement of a claim based on a material default by Censtor
        of a Secured Obligation within thirty (30) days after the date of final
        determination of such claim, RRC shall have the right to proceed against
        the security interest as provided under Section 2.3, including all
        rights of a secured party under the California Uniform Commercial Code,
        in addition to any other rights it may have in law or equity.

        7.3  Remedies for Insolvency.  RRC shall have the right to exercise the
        security interest cited under Section 2.3, in addition to any other
        rights it may have in law and equity, by


                                       8
<PAGE>   9
        writing immediately if Censtor (i) voluntarily or involuntarily becomes
        the subject of a petition in bankruptcy or of any proceeding relating to
        insolvency, receivership, liquidation, or composition for the benefit of
        creditors; or (ii) admits in writing its inability to pay its debts as
        they become due.

        7.4     Survival. The rights and obligations under Sections 2, 3, 4, 5,
        6, 8 and 9 shall survive termination of this Agreement.
